US Faces 8-Week Oil Price Shock if Iran War Drags

An internal White House risk assessment has concluded a war with Iran lasting 8-to-12 weeks would trigger a significant oil and gasoline price shock, with Treasury Secretary Besant warning President Trump that US allies in Asia and Europe would bear the brunt of the economic fallout. The warning, reported by the Wall Street Journal on April 12, underscores the intense economic risk calculations underway within the administration as it navigates a fragile ceasefire.

"A prolonged conflict would cause a 'significant and sustained oil and commodity price shock,' which could lead to stickier inflation and ultimately higher interest rates," JPMorgan Chase & Co. Chief Executive Officer Jamie Dimon warned in a recent letter to shareholders.

The economic strain is already materializing, with the March Consumer Price Index jumping 3.3% year-over-year, up from 2.4% in February, according to data from the Bureau of Labor Statistics. WTI crude oil prices briefly topped $100 a barrel, pushing average US gasoline prices above $4 a gallon, reflecting market anxiety over the conflict's duration.

The critical 8-to-12-week window identified by Besant highlights the administration's focus on avoiding a protracted conflict that could derail the domestic economy and destabilize global energy markets. The Treasury has already issued a short-term authorization to permit the sale of Iranian oil currently in transit on the water, a move seen as a temporary measure to alleviate immediate supply pressures.

Strait of Hormuz Blockade Threatens 20% of Global Oil

CEOs from three major US oil companies have privately cautioned the administration that a long-term closure of the Strait of Hormuz—a chokepoint for about 20% of the world's daily oil and liquefied natural gas supply—would severely constrict global fuel supply chains. Chevron CEO Mike Wirth stated last month that financial markets have not fully priced in the severity of a physical disruption to oil flows.

While Energy Secretary Chris Wright and Interior Secretary Doug Burgum assured oil executives that passage through the strait would be resolved in "weeks, not months," some executives reportedly expressed frustration with what they see as an overly optimistic timeline from the government.

Fertilizer Costs Hit US Farmers as Supply Chain Snaps

The war's economic repercussions are also hitting the U.S. agriculture sector, primarily through the supply of fertilizers. Approximately half of the global supply of urea and nearly a third of ammonia travels through the Strait of Hormuz, according to the American Farm Bureau Federation.

"It's an emergency for our farmers, and we need that supply line reopened," said Caleb Ragland, president of the American Soybean Association, after a meeting with Agriculture Secretary Brooke Rollins. The message from the agricultural community is clear: the war cannot be allowed to drag on.

However, not all assessments are pessimistic. Matt Coday, founder and president of the Oil and Gas Workers Association, characterized the gasoline price hikes as "temporary fluctuations," stating he does not anticipate a major shock to the US economy.
